PVC insulated wire and cable (commonly known as plastic insulated wire), consumers should pay attention to the following points when purchasing and using plastic wires:

Select products of good quality, high reputation, and after-sales service. Pay attention to the product's logo. General plastic insulated wire product labels should be marked with the name of the plant, site, rated voltage, specifications and models, length, "3C" certification number, inspection qualified chapter, production date, etc., in particular, should be printed on the cable wires including the name of the plant, Continuity mark including rated voltage and type.

Check the appearance of the product. The appearance of regular products should be smooth, round and uniform in color. The outer layer of insulated wires should have a bright color and fine texture. The conductors should be made of electrolytic copper, and the outer layer should be bright and slightly soft. The non-formal products should be made of recycled plastics, with dull color and loose texture. The copper is dark and hard, and it is a regenerative hybrid copper. It has a high resistivity, poor electrical conductivity, and can be heated in use without being safe.

Use a pair of scissors to inject a small piece of insulation and check that the insulation thickness is uniform (not biased). The plastic is dense and airless.

When purchasing plastic insulated wire products, it is best to consult an experienced professional electrician because the current carrying capacity of the wire is related to the cross section of the wire, the material of the wire (aluminum or copper), the type, and the laying method (open coat or tube) ) and environmental temperature and so on.

In the use of plastic wire, must be properly wired, generally best by a professional electrician wiring, their wiring, pay attention to the insulation wire joints, should be firmly connected, do not simply use a tape tangled together, so that after the power connector is easy to heat.
